The trench coat, like a motorcycle jacket or a pair of jeans, is one of those basics that can be endlessly reinvented while still maintaining its design integrity. For next Resort, newness comes from sleeveless versions, color or fabric-blocking, cape-like slits for arms or puff-shouldered sleeves with channel-elastic cuffs. Fabrics include rustic linens, smooth cottons, lightweight corduroy and flat-quilted nylon. Novel touches can be as splashy as floral-appliquéd shoulders or as subtle as a single red button.
